Researchers have made a surprising new discovery in the structure of the centromere, a structure that is involved in ensuring that chromosomes are segregated properly when a cell divides. Mistakes in ...

In a major leap forward for genetic and biomedical research, two scientists at the University of Missouri have developed a powerful new artificial intelligence tool that can predict the 3D shape of ...

Scientists have taken a detailed look inside the small, densely packed structure of the inactive X chromosome found in female mammals called the Barr body. Scientists at UMass Medical School, the ...

WHEN a great physicist takes the trouble to explain in simple language some of his matured thoughts on topics of general interest outside his own subject, it is an event for which one cannot be too ...

In many species, the sex chromosomes are unequally distributed: in humans as well as in the model organism Drosophila melanogaster male cells only possess one X chromosome, unlike female cells, which ...

One of the challenges of working with ancient DNA samples is that damage accumulates over time, breaking up the structure of the double helix into ever smaller fragments. In the samples we’ve worked ...
